Tom Foster 18f8f1701c feat(docker): optimise Node.js installation to single version per image 
Replace multi-version Node.js installations with targeted single-version approach
to reduce image size and eliminate unused binaries. Updates version detection logic
to provide three distinct categories: previous LTS, current LTS, and latest stable.

Each distribution variant now installs exactly one Node.js version aligned with
its maturity level, simplifying builds and creating more predictable environments.

Check Node.js Versions Action

A Forgejo/GitHub Actions composite action that queries the official Node.js release schedule to find currently supported versions.

Usage

- name: Check Node.js versions
  id: node-check
  uses: ./.forgejo/actions/check-nodejs-versions

- name: Display results
  run: |
    echo "LTS versions: ${{ steps.node-check.outputs.lts-versions }}"
    echo "All supported versions: ${{ steps.node-check.outputs.live-versions }}"

Outputs

Output Description Example
lts-versions Space-separated list of Node.js LTS versions 18 20 22
live-versions Space-separated list of all supported Node.js versions 18 20 22 24

How it works

  1. Queries the official Node.js release schedule from GitHub
  2. Filters for currently supported versions (between start and end dates)
  3. Excludes odd-numbered versions (development/unstable releases)
  4. Identifies which versions are LTS
  5. Returns sorted lists of version numbers

Example workflow usage

name: Build with dynamic Node.js versions
on: [push]

jobs:
  check-node:
    runs-on: ubuntu-latest
    outputs:
      lts-versions: ${{ steps.check.outputs.lts-versions }}
      live-versions: ${{ steps.check.outputs.live-versions }}
    steps:
      - uses: actions/checkout@v4
      - id: check
        uses: ./.forgejo/actions/check-nodejs-versions

  build-lts:
    needs: check-node
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node: ${{ fromJSON(format('[{0}]', replace(needs.check-node.outputs.lts-versions, ' ', ','))) }}
    steps:
      - name: Build with Node.js ${{ matrix.node }}
        run: echo "Building with Node.js ${{ matrix.node }}"

Notes

  • Only returns even-numbered versions (stable releases)
  • LTS versions are only included after their LTS start date
  • Version numbers are returned without the 'v' prefix
